This sentiment is part of what inspired PG Casts. The database can do lots of powerful things that framework ORMs tend to keep in the shadows. We want to make the DB more accessible!
An important part of this (that I've still not really figured out) is, if you're pushing much of your validation in the DB, how & where to interpret the different validation errors you might receive, and pass back through your application for turning into friendly messages, highlighting formfields, etc, etc.
I started an awesome postgres SQL repo on github but haven't started to commit to It. I think we share a common goal, but mine isn't as ambitious in that video requires even more effort!
